Question

我正在尝试更改应用程序的语言，但它没有发生。我已尝试过几乎所有可用的解决方案，但都没有。有趣的是，大多数代码都能够更改Facebook Account Kit活动的语言，但其他活动的语言没有被更改.Below是我的应用程序类和清单文件。

public class MyApplication extends Application {


    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
        Configuration config = getBaseContext().getResources().getConfiguration();

        new SharedPrefManager(this).setLanguage("fr");
        String lang = new SharedPrefManager(this).getLanguage();

        locale = new Locale(lang);
        Locale.setDefault(locale);
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        AccountKit.initialize(getApplicationContext());
    }


}

您可以更改语言（i18N），如下所示：

public static void changeLanguage(String language, Context context) {
    try {
        if ( null != language) {
            Locale locale = new Locale(language); 
            Locale.setDefault(locale);
            Configuration config = new Configuration();
            config.locale = locale;
            context.getResources().updateConfiguration(config, context.getResources().getDisplayMetrics());
        }

        Log.i(TAG, "Language changed to " + language);
    } catch (Exception e) {
        Log.e(TAG, "[changeLanguage]" + e.getMessage());
    }

}
